Right. My point is that the Arab states lost to Israel because Israel was backed by the West. Without western support, a tiny Jewish state with almost no natural resources and a small population would be hard-pressed to stand its ground against a coalition of Arab states with a much larger population, oil money, and possible Russian backing. All the Arab states would need to do is keep taking pot shots at Israel while their superior military technology degrades and their stockpiles dwindle. A modern fighter jet relies on thousands of hyper-specific, high precision parts which can only be sources from western manufacturers. One part breaks and your whole plane is grounded. Even if the Arab states are not in great shape themselves, they win a war of attrition handily - especially once the average Israeli sees the inevitable and flees, depriving Israel of its soldiers and intellectual economy.

Otoh, your timeline argument is reasonable, and I wouldn't be surprised if this wasn't a coincidence in one way or another.

What makes you think any arab nation cares about the Palestinians' well-being?

You seem to be entirely ignoring comtinual efforts to prevent them from becoming so empowered including murdering their scientists, bribing their leaders, drawing up agreements and them just not pushing it because the natural and expected results is war.

It is reasonable to expect that any given year the US would rather kill them all rather than let them have nukes.
